Abstract (en)
[origin: WO2010086009A1] The invention relates to an improved multi-stage centrifugal compressor (10) comprising at least four centrifugal compression stages (11,12,13,14), each including an impeller. The impellers of one pair of the stages (12,13) are mounted on a first shaft (23) coupled to a first high speed direct drive motor (16), and the impellers of another pair of the stages (11,14) are mounted on a second shaft (24) coupled to a second high speed direct drive motor (15). The speed of the first and second motors is controlled by at least one drive (25) such that the impellers are all driven at the same speed.
